Meet the E-TAC Electrolyzer
Next generation electrolysis for the lowest levelized cost of Hydrogen
H2Pro's E-TAC electrolyzer produces green hydrogen at 95% energy efficiency (compared to 60-70% of conventional systems). This breakthrough efficiency combined with E-TAC's reduced cost of materials, easily scalable membraneless design, and high compatibility with renewables will allow H2Pro systems to deliver green hydrogen at lowest cost.

E-TAC Benefits
H2pro operates at the cutting edge of green hydrogen technology. Our two-phase, membraneless process offers a variety of benefits that make affordable green hydrogen a reality.
LOWEST OPEX
E-TAC reaches its unparalleled 95% efficiency (compared to 60-70% efficiency of alternative methods) by avoiding the inefficient electrochemical Oxygen Evolution Reaction of conventional electrolysis, replacing it with a Thermally Activated Chemical (TAC) reaction that doesn't consume power or heat. The system level efficiency amounts to only 42 kWh/kg H2 (i.e. 95% based on HHV), significantly reducing operating costs.
INTERMITTENCY COMPATIBLE
The system design allows a flexible operational scheme, making it compatible with a wide range of partial power loads. The inherently dynamic two-phase process is a perfect fit to the fluctuating nature of renewable energy. This means our systems work well with intermittent renewable energy sources, like solar and wind.
LOW CAPEX
In E-TAC, the proprietary anode is sourced from nickel - a cheap and readily available metal (whereas conventional electrolysis requires rare, costly metals like Platinum and Iridium to be used for the electrodes). Nickel supply chains are not expected to suffer any difficulties in the future, as opposed to other rare metals. Additionally, since hydrogen and oxygen generation are time-separated, an expensive membrane is not required. Eliminating the need for a membrane and using low-cost, mass produced electrodes greatly reduces capital expenditures.
HIGH PRESSURE
The two-phase process and membrane-free structure facilitates hydrogen production at 45 bar as a standard offering. The higher outlet pressure eliminates the need for subsequent compression in almost all applications.
SAFER CONFIGURATION
Hydrogen and oxygen are produced at different times, so they are never in danger of mixing. In conventional electrolysis only a thin membrane separates hydrogen and oxygen gas flows, which may form an explosive mixture.
NO HEAT REMOVAL REQUIRED
Our systems do not require dissipation of large amounts of low grade heat due to the 95% system efficiency. In conventional electrolysis, up to 30-40% of the electrical power in put is transformed to low grade heat, which cannot be used and thus need to be dissipated in air coolers or cooling towers. Avoiding this saves CAPEX, OPEX and plot space.
Made for Utility Scale
Tackling a problem as vast as climate change demands solutions of equal magnitude - that is why we're designing our systems for maximal impact in utility scale applications. Explore the journey our technology will take to be deployed in the largest green hydrogen projects.

Why Green Hydrogen?
Green Hydrogen is the missing piece in the puzzle to put fossil fuels behind us
Green hydrogen, produced using renewable energy, offers a clean energy alternative to fossil fuels. An extremely versatile molecule, it can store and transport surplus renewable energy and decarbonize hard-to-electrify sectors like heavy industry and aviation. In the coming decades, expanded applications of green hydrogen are projected to drive demand to 500-600 million tonnes per year, representing a multi-trillion dollar market.
